Tank Overhaul.... thought i would share
 

So the story starts a couple years ago with me being fairly inexperienced around saltwater and getting a 180 gallon tank. I drilled the tank myself and built an internal overflow box. now both of those things i ended up doing wrong, I drilled a single downpipe and built a massive overflow box.

Fast forward to last week. I was tired of my tank being loud and was also tired of worrying about a flood. All of that plus the fact that my oversized overflow restricted my ability to get flow around the back side of the rock structure, resulting in a large amount of detritus accumulating in the dead spots.

Soooo. i decided i would set up a holding tank and remove EVERYTHING from the tank and sump so i could do things right. or at least better.

Here is the tank before the tear down. Notice the oversized overflow.

Here is a sideview. Almost impossible to get proper flow around the rock structure.

Brought in a holding tank for the fish and coral during the overhaul.

All said and done it was alot of work but definitely worth it in the end.
The tank now runs silent and i have an emergency drain as well so i can sleep at night without fear of a flood. Didnt lose any livestock during the transfers either so all in all must consider it a sucess.

Great job, looks really good
Enjoy

Wow nicely done! Love the new (old) tank!

Thanx. I appreciate the kind words guys.

I even decided to order some led lighting to finish off the overhaul.
Should be in next week and then im all done.

What a makeover! From the pics everything looked like it went out as planned. Love the new overflow box over the old one!!

Im monitoring to make sure i dont get any ammonia spikes, but yeah so far so good. The overflow definitely made everything much more functional and opened up the tank nicely.

Great looking makeover job, with the addition of the emergency drain for peace of mind and the smaller box. I used a small OF box at the top back of my 90 g too so the back is opened up more for aquascaping, sand bed and more swimming area for the fish. I think it looks better as well. :rockon:
